What it is measuring
Progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1) by Blinded Independent Central Review (BICR)
This is the trial's main question — the one it is designed and sized to answer. Anything else it reports is a secondary finding, and secondary findings are far more likely to be chance.
Phase 3. Compares the treatment against current standard care in a large group. This is the design that changes practice.
How the researchers describe it
The purpose of this study is to learn more about a new medicine called PF-08634404, and how well it works in people with cancer of the colon or rectum (CRC)). The goal is to understand if the new study medicine, combined with chemotherapy that is approved for colorectal cancer, can help people whose cancer has spread or returned after treatments taken before.
To join the study, participants must meet the following conditions:
* Be 18 years or older.
* Have colorectal cancer that has spread to other parts of your body.
* Be in good enough health to receive study treatment.
* Should not be pregnant before starting treatment.Participants will be randomized (like flipping a coin) to one of 2 different treatment arms. The first arm (Arm A) will include the new medicine PF-08634404 in combination with chemotherapy that is approved for colorectal cancer, and the second arm (Arm B) will include an approved medicine for colorectal cancer, called Bevacizumab, in combination with chemotherapy that is approved for this type of cancer. Participants and their doctors will not know which arm they are being assigned to. Participants will receive all the study medications through intravenous (IV) infusions, which means the medicine is given directly into a vein.

Who the trial is looking for
Inclusion Criteria
- Histological or cytological confirmed colorectal adenocarcinoma.
- Evidence of Stage IV metastatic disease.
- No prior systemic therapy for metastatic disease.
- Eastern Cooperative Oncology Group performance status (ECOG) 0-1

Exclusion Criteria
Participants are excluded from the study if any of the following criteria apply:

Where it is running
Running at 285 sites. Listed in: Argentina, Australia, Belgium, Brazil, Canada, China, Denmark, France, Germany, Israel, Italy, Japan, Poland, Puerto Rico, Spain, Taiwan, United States.
Individual hospitals, and whether each is currently open, are listed on the registry record. Sites open and close throughout a trial.
Worth asking your oncology team
Being listed here is not a recommendation, and no one page can tell you whether a trial is right for you. These are the questions it raises.
- Is this trial open at a hospital I could realistically travel to?
- Given my stage, my previous treatment and my tumour's molecular profile, would I be eligible?
- What would I be giving up by joining — is the comparison arm the treatment I would otherwise be having?
- What is already known about the safety of what is being tested?
